Healthcare companies were well-represented on the list — they accounted for 20% of it — so we decided to rank them separately. The industry ranks shuffled a bit from last year, with pharmaceutical company Bristol-Myers Squibb jumping up one spot to take first place and last year’s No. 1, Amgen, dropping down to No. 5.

To create the list, PayScale ranked companies on the 2015 Fortune 500 list against its salary and survey database, homing in on six criteria: high job satisfaction, low job stress, ability to telecommute, high job meaning, experienced median pay (for employees with at least five years of experience), and whether a company pays above or below market price for their employees. Read a detailed breakdown of the methodology here.
